Dinosaur Ant
Nothomyrmecia macropsAlso known as Dawn Ant
Widely regarded as a living fossil among social insects, this ancient ant retains primitive anatomical features such as unspecialized abdominal segments and rudimentary social communication. Workers emerge strictly on chilly nights when temperatures drop below ten degrees Celsius, allowing them to hunt solitary insects while thermophilic competitors remain dormant. Colonies consist of only a few dozen to a hundred individuals nesting underground beneath the roots of old-growth Eucalyptus trees.
